Don Meij, the chief executive of Domino’s Pizza Enterprises, said: “We’ve always said that it doesn’t make sense to have a 2-tonne machine delivering a 2kg order.”

Last year, New Zealand became one of the first countries to allow commercial drone deliveries. Speaking after the Domino’s test flight, the transport minister, Simon Bridges, said: “Our enabling laws and regulation means we have the ideal environment.”

But Philip Solaris, the director of drone company X-craft Enterprises, said Domino’s could be hampered by a rule requiring drones to be kept in sight at all times.

“I can’t truly see how commercially viable that idea is, because you would have to literally have somebody walking along to keep it in the line of sight, watching it at all times,” he said, adding that Domino’s would need to avoid “random hazards [such as] power lines, moving vehicles, children in the backyard playing”.

The Domino’s and 7-Eleven deliveries were carried out using drones from US-based company Flirtey.

Domino’s said it was looking into opportunities for drone delivery trials in Australia, Belgium, France, the Netherlands, Japan and Germany.

Drone deliveries will be legal in Australia next month, providing they stay at least 100ft (30 metres) away from houses.
